The detection of this sub-clade once again raises concerns that this
sub-clade is transmitting in humans. Public swine sequences
collected since the West Virginia cluster are heavily weighted toward
the earlier sequence (13/15 matches) although one of the two swine
matches with recent human cases is from Indiana (A/swine/Indiana/A01203509/2012)collected on May 5, 2012).

The CDC is commended for the rapid release of these important sequences.
